CAUTION:
Be sure to perform AIR BAG DIAGNOSTIC SYSTEM CHECK before starting diagnosis according to
flow table.
When measurement of resistance or voltage is required in this table, use a tester along with a cor-
rect terminal adapter from special tool (Connector test adapter kit).
When a check for proper connection is required, refer to INTERMITTENT AND POOR CONNEC-
TIONS in this section.
If there is open circuit in the air bag wire harness, connector or terminal is found damaged, replace
the wire harness, connector and terminal as an assembly.

module or disassemble it. Otherwise personal injury may
result.
CAUTION:
If air bag (Inflator) module was dropped from a height or
90 cm (3 ft) or more, it should be replaced.

6) Stretch the deployment harness from the driver or passen-
ger air bag (inflator) module to its full length 10 m (33 ft) (1).
Special tool
(A) : 09932-75030
7) Place a power source (3) near the shorted end of the deploy-
ment harness. Recommended application: 12 Volts mini-
mum, 2 amps minimum. A vehicle battery is suggested.
8) Verify that the area around the air bag (inflator) module or
seat belt pretensioner is clear of all people and loose or flam-
mable objects.
9) Verify setting condition of air bag (inflator) module or preten-
sioner as follows.
[In case of driver air bag (inflater) module]
Verify that the driver air bag (inflator) module is resting with
its vinyl trim cover facing up.
[In case of passenger air bag (inflator) module]
Verify that the passenger air bag (inflator) module is firmly
and properly secured in passenger air bag (inflator) module
deployment fixture (special tool).
[In case of seat belt pretensioner]
Verify that the seat belt pretensioner, is placed as shown in
the figure on the ground in the space just cleared.
10) Connect (2) the air bag (inflator) module or seat belt preten-
sioner to the deployment harness connector and lock con-
nector with lock lever.
11) Notify all people in the immediate area that you intend to
deploy/activate the air bag (inflator) module or seat belt pre-
tensioner.
NOTE:
When the air bag deploys and the pretensioner acti-
vates, the rapid gas expansion will create a substantial
report. Wear suitable ear protection. Notify all people
in the immediate area that you intend to deploy the air
bag (inflator) module or activate the seat belt preten-
sioner and suitable ear protection should be worn.
When the driver air bag deploys and the pretensioner
activates, driver air bag (inflator) module and preten-
sioner (retractor assembly) may jump about 30 cm (1
ft) vertically. This is a normal reaction of them to the
force of the rapid gas expansion inside the air bag and
pretensioner.
After the air bag (inflator) module has been deployed,
the surface of the air bag may contain a powdery resi-
due. This powder consists primarily of cornstarch
(used to lubricate the bag as it inflates) and by-prod-
ucts of the chemical reaction.

12) Separate (1) the two banana plugs on the deployment har-
ness.
13) Connect the deployment harness to the power source (12V
vehicle battery) (2) to immediately deploy/activate the air
bag or seat belt pretensioner.
14) Disconnect the deployment harness from power source (12V
vehicle battery) (2) and short (3) the two deployment har-
ness leads together by fully seating one banana plug into the
other.
15) In the unlikely event that the air bag (inflator) module or seat
belt pretensioner did not deploy/activate after following these
procedures, proceed immediately with Steps 20) through
23). If the air bag (inflator) module or the seat belt preten-
sioner did deploy/activate, proceed with Steps 16) through
19).
16) Put on a pair of shop gloves to protect your hands from pos-
sible irritation and heat when handling the deployed air bag
(inflator) module and the activated seat belt pretensioner.
17) Disconnect the deployment harness from the air bag (infla-
tor) module and the seat belt pretensioner as soon after
deployment/activation as possible.
This will prevent damage to the deployment harness due to
possible contact with the hot air bag (inflator) module and
seat belt pretentioner. The deployment harness are
designed to be reused. They should, however, be inspected
for damage after each deployment/activation and replaced it
if necessary. WARNING:
After deployment/activation, the metal surfaces of the
air bag (inflator) module and the seat belt pretensioner
will be very hot. Do not touch the metal areas of them
for about 30 minutes after deployment/activation.
Do not place the deployed air bag (inflator) module and
the activated seat belt pretensioner near any flamma-
ble objects.
Do not apply water, oil, etc. to deployed air bag (infla-
tor) module and activated seat belt pretensioner.
If the deployed air bag (inflator) module and the acti-
vated seat belt pretensioner must be moved before it is
cool, wear gloves and handle it by using nonmetal
material such as the air bag, webbing and vinyl trim.
Failure to follow procedures may result in fire or per-
sonal injury.

8) Route deployment harness out the vehicle.
9) Verify that the inside of the vehicle and the area surrounding
the vehicle are clear of all people and loose or flammable
objects.
10) Stretch the deployment harness to its full length 10 m (33 ft)
(1).
Special tool
(A) : 09932-75030
11) Place a power source near the shorted end (3) of the deploy-
ment harness. Recommended application: 12 Volts mini-
mum, 2 amps minimum. A vehicle battery is suggested.
12) Completely cover windshield area and front door window
openings with a drop cloth, blanket to similar item (2). This
reduces the possibility of injury due to possible fragmenta-
tion of the vehicle’s glass or interior.
13) Notify all people in the immediate area that you intend to
deploy the air bag (inflator) module or activate the seat belt
pretensioner.
.
NOTE:
When the air bag deploys and the pretensioner acti-
vates, the rapid gas expansion will create a substantial
report. Wear suitable ear protection. Notify all people
in the immediate area that you intend to deploy the air
bag (inflator) module or to activate the seat belt preten-
sioner and suitable ear protection should be worn.

ucts of the chemical reaction.
WARNING:
After deployment/activation, the metal surfaces of the
air bag (inflator) module and the seat belt pretensioner
will be very hot. Do not touch the metal areas of them
for about 30 minutes after deployment/activation.
Do not apply water, oil, etc. to deployed air bag (infla-
tor) module and activated seat belt pretensioner. Fail-
ure to follow procedures may result in fire or personal
injury.
